A method for degrading a readily degradable resin composition comprising an aliphatic polyester (A) which is biodegradable, and an aliphatic polyester (B) which releases an acid upon hydrolysis and which is biodegradable at a higher degradation rate than that of the aliphatic polyester (A), the method comprising degrading the readily degradable resin composition in an enzyme reaction liquid containing a degradation enzyme, and an acid neutralizing agent incompatible with the enzyme reaction liquid.


This invention provides a plastic container characterized in that an expanded layer comprising expanded cells having a flat shape with an average major axis of not more than 400 m and an average aspect ratio (L/t) of not less than 6 as viewed in cross section of the container wall along the maximum stretch direction, which are oriented in the stretch direction and are distributed so as to be superimposed on top of each other in the thickness-wise direction, is formed within the container wall. In this container, expanded cells having a flat shape are distributed so as to orient in a given direction and, thus, has light shielding properties and has a pearl-like appearance, that is, has a very high commercial value. Further, since any colorant is not contained, the suitability for recycling is excellent.

A method of producing a powder of fatty acid metal salt for forming ultrafine metal particles includes washing the fatty acid metal salt so that the amount of unreacted substance or by-product is 4.0 mol % or less when the fatty acid metal salt is formed; preparing a pressed cake by pressing the fatty acid metal salt; and drying the pressed cake so that the water content is 200 ppm or less. The powder has a property for deodorizing mercaptan smelling components and/or a property for inactivating microproteins.

An object of the present invention is to provide a method for efficiently producing an oligomer or a monomer by degrading a biodegradable resin using an enzyme, so that the oligomer or the monomer can be recovered. The present invention provides a method for producing an oligomer and/or a monomer by degrading a biodegradable resin in a degradation liquid containing a biodegradation enzyme, a buffer agent, an organic solvent, and water. In this method, the SP value of the organic solvent is less than 8.5 or more than 11.5, and the percentage content of the organic solvent (by volume) in the degradation liquid is higher than 1% and lower than 15%. In the method for producing an oligomer or a monomer, the degradation percentage of the biodegradable resin is low, and deposits of aggregates of the oligomer and/or the monomer are few, so that the recovery percentage is high.


This invention provides a plastic container (20) characterized in that an expanded layer comprising expanded cells (1) having a flat shape with an average major axis of not more than 400 pm and an average aspect ratio (L/t) of not less than 6 as viewed in cross section of the container wall along the maximum stretch direction, which are oriented in the stretch direction and are distributed so as to be superimposed on top of each other in the thickness-wise direction, is formed within the container wall. In this container, expanded cells having a flat shape are distributed so as to orient in a given direction and, thus, has light shielding properties and has a pearl-like appearance, that is, has a very high commercial value. Further, since any colorant is not contained, the suitability for recycling is also excellent.


Cell aggregate formation control and cell aggregate disintegration control are carried out with respect to cells in a culture container to increase cell proliferation efficiency. The number of the cells in the culture container is counted without disassembly of a culture system and irrespective of the density of the cells. An external force is applied to the culture container to carry out at least one of cell aggregate formation control and cell aggregate disintegration control with respect to cells in the culture container, thus culturing the cells. The external force is applied to the culture container by pressing an agitating member onto a top surface of the culture container placed in flat orientation to a predetermined pressing degree, and moving the agitating member in a horizontal direction at a predetermined speed, thus controlling at least one of cell aggregate formation and cell aggregate disintegration with respect to the cells in the culture container. A method for counting counted targets disposed in a liquid enclosed in a container includes adjusting a thickness of at least a part of the container. At least a part of the adjusted part is set as a measurement target region. A number of counted targets in the measurement target region is counted.

A multilayered container with excellent heat resistance which is obtained by melt molding and has an interlayer made of an oxygen-absorbing barrier resin composition. The multilayered container comprises inner and outer layers comprising an olefin resin and, sandwiched between the inner and outer layers, an interlayer made of an oxygen-absorbing barrier resin composition. The multilayered container is one formed by melt molding. In thermal analysis of a container barrel part, it has a quantity of heat of isothermal crystallization after heating from 30 C. to 130 C. at 100 C./min of 0.5 J/g or larger. In the analysis, the barrel part, after cooling from 200 C. to 130 C. at 100 C./min, gives an isothermal crystallization profile in which the time period to a peak top is shorter than that in a multilayered container including an interlayer consisting only of the base resin (oxygen-barrier resin) constituting the oxygen-absorbing barrier resin composition.
